ApplicatorrAlgust' 2, 1944; Serial-N0; `5473101 1 claim.; (ci. rsf-saarThis inventionfrelates to scissors and shears Sharpeners, and the chiefobject of the invention is to provide simple, ellicient and practicalmeans for sharpening such implements, and that may be easily and readilyused and operated by individuals, even though not expert in such work.

A further object of the invention is to provide a scissors and shearsSharpener including a flat and horizontally disposed table, means at therear end of the table for releasably engaging a blade of a pair ofscissors or shears and supporting the blade in proper position relativeto the `table for bevel sharpening the same, and a le with means on thehandle thereof for slidably supporting the handle in proper spacedrelation to the upper face of the table, said spacing corresponding tothe spacing of the upturned edge of the scissors or shears blade abovethe table, as supported at the rear end of the table, and whereby thefile may be moved and reciprocated smoothly and evenly over the cuttingedge of the blade for sharpening same.

With the stated objects in view, together with such other and additionalobjects and advantages as may be pointed out in the specification,attention is directed to the accompanying drawing, wherein Figure 1 is aside elevation of the Sharpener as in use, the scissors blade asreleasably mounted at the rear end of the table being shown in section,the device being shown as resting upon a support.

Figure 2 is a plan view of the assembly as shown in Figure 1, drawn on asomewhat enlarged scale.

Figure 3 is a rear end elevation of the assembly of Figures 1 and 2 andFigure 4 is a fragmentary View in side elevation of the mechanism at therear end of the table for releasably and adjustably clamping and holdinga scissors blade for sharpening.

` The invention comprises a suitable oblong table represented generallyat 5, and which is supported upon a down-turned end flange `6 at itsforward end, and at its rear end by the down-ward extension of the outerclamp-plate l. The clampplate 'I has its upper margin turned inwardly asindicated at 'Ia so as to enable this element to more closely conform tothe contour of a shear or scissor blade in manner later to be ppintedout. The clamp plate I is adjustably clamped to the inner clamp-plate 8by means of short bolts 9 passed through the two plates and provided attheir inner ends with thumb-nuts 9a, and by which arrangement the twoplates tightened upon a shear or scissor blade I positioned edge upwardbetweenfthe uppenzm'arglnsmf'tlieszmzllatay Itis:` to the. notedzthattheboltslare: spaced suma@ ciently below the upper edges of the plates toafford room for the insertion of the blade. Ears II are turned down inlaterally spaced relation from the rear end of the table 5 and similarears I2 are turned inwardly from the lower margin of the innerclamp-plate 8 and adapted to overlle the ears II of the table 5. A pivotbolt I3 is passed through the two sets of overlying ears II and I2,whereby the clamp-plates I and 8 are pivotally supported at the rear endof the table 5 and transversely thereof, and may be tilted more or lessangularly to the surface of the table for a purpose to be described. Anelongated tab I4 is struck out and turned down at the rear end of thetable 5, inwardly spaced from the rear end thereof, and another tab I5is similarly struck out at the lower margin of the outer clamp-plate 'Iand is turned inwardly in longitudinal alignment with the tab I4. Anadjustment link I6 is provided and is pivoted at I'I by its outer end tothe tab I5, while the inner end of this link is adjustably connected tothe tab I4 by means of a bolt I8 passed through the tab I4 and throughan elongated slot I6a formed in the inner end of the link Iii. The boltI8 is provided with a thumb nut I8a. By this arrangement theclamp-plates I and 8 may be tilted to any desired angle and there lockedby turning up the thumb nut I8a.

The sharpening element of the assembly consists of a le I9 provided withthe handle 20, the latter having mounted at the under side thereof aslide-knob 2I. 'I'he iile is of the conventional flat type, and the knob2| is of such size or length as to maintain the ille blade when laidacross the upper edges of the clamp-plates 'I and 8, in a substantiallyparallel relation to the surface of the table 5, and so that the illeblade will move and reciprocate smoothly and evenly over these plates,Without any up and down movement to the file, or at least the minimumamount of such motion that may be possible.

In use one of the blades I0 of the scissors or shears is positionedbetween the upper margins of the plates 'I and 8 with the cutting edgeof the blade turned inwardly. The plates 1 and 8 are then tiltedinwardly as may be required for sharpening the blade with the desireddegree of bevel. The thumb-nuts 9a are then turned up for tightening theplates 'I and 8 upon the blade III, and the thumb-nut I 8a is turned upfor locking the plates to the selected adjustment. The describedmounting of the blade In is such that the upturned cutting edge is justexposed above the edges of the plates 1 and 8. The le blade I9 is thenlaid across the edge of the blade lll, and with the slide-knob 2 lturned downward and bearing upon the surface of the table 5, the le isreciprocated back and forth over the cutting edge of the blade, thussharpening same smoothly and evenly. In this operation the file is ofcourse moved uniformly from end to end of the blade, so as to sharpensame equally from end to end.

While I havehere shown and described a pre-` ferred embodiment Jrof' theinvention, ltogether with certain preferred structural features thereof,the embodiment shown as well as the several structural features thereof,may be changed inA details as desired, within the scope ofthe claim.
